Some integral inequalities for operator monotonic functions on Hilbert spaces

open access: yesSpecial Matrices, 2020
Let f be an operator monotonic function on I and A, B∈I (H), the class of all selfadjoint operators with spectra in I. Assume that p : [0.1], →ℝ is non-decreasing on [0, 1].

Dose Dependence of the Separate and Combined Impact of Copper-Oxide and Selenium-Oxide Nanoparticles on Oxygen Consumption by Cells With or Without the Background Action of Some Modulators of the Mitochondrial Respiratory Function

open access: yesDose-Response, 2023
We had previously demonstrated on various stable cell cultures exposed to chemically different nanoparticles when assessing their cytotoxicity by different outcomes, dose-response relationships may be either monotonic or non-monotonic falling within an ...

Monotonicity and complete monotonicity of some functions involving the modified Bessel functions of the second kind

open access: yesComptes Rendus. Mathématique, 2023
In this paper, we introduce some monotonicity rules for the ratio of integrals. Furthermore, we demonstrate that the function $-T_{\nu ,\alpha ,\beta }(s)$ is completely monotonic in $s$ and absolutely monotonic in $\nu $ if and only if $\beta \ge 1 ...

Sharp bounds for a ratio of the q-gamma function in terms of the q-digamma function

open access: yesJournal of Inequalities and Applications, 2021
In the present paper, we introduce sharp upper and lower bounds to the ratio of two q-gamma functions Γ q ( x + 1 ) / Γ q ( x + s ) ${\Gamma }_{q}(x+1)/{\Gamma }_{q}(x+s)$ for all real number s and 0 < q ≠ 1 $0< q\neq1$ in terms of the q-digamma function.

Robust chaos generation by a perceptron

open access: yes, 2000
The properties of time series generated by a perceptron with monotonic and non-monotonic transfer function, where the next input vector is determined from past output values, are examined.

On testing exponentiality under Type-I censoring

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
Two new goodness-of-fit testing procedures are introduced to test exponentiality when data are subject to Type-I censoring. We proposed four test statistics for this purpose.

The monotonicity of the permanent function

open access: yesDiscrete Mathematics, 1991
The author shows that for each positive integer \(n\) there exists \(\alpha_ n\in(0,1)\) such that \(\text{per}[(1-\theta)J_ n+\theta S]\leq\text{per} S\) for all \(0\leq\theta\leq\alpha_ n\) and all \(n\times n\) doubly stochastic matrices \(S\).

Two Approximation Formulas for Bateman’s G-Function with Bounded Monotonic Errors

open access: yesMathematics, 2022
Two new approximation formulas for Bateman’s G-function are presented with strictly monotonic error functions and we deduced their sharp bounds. We also studied the completely monotonic (CM) degrees of two functions involving G(r), deducing two of its ...
